Car Care Tips and Maintenance

Manufacturers Scheduled Maintenance
All vehicle manufacturers produce a maintenance schedule for each vehicle that they build. These maintenance
schedules are designed to optimize the safety and dependability of your vehicle. In most cases, if the schedule is adhered to
along with periodic inspections it will decrease operating costs and minimize repair bills.

Oil Changes
Larry's Auto and Truck carries the complete line of Valvoline oil products. Use 10w30 for normal summer driving, 5w30 for
winter driving, Maxlife semi-synthetic for high mileage vehicle with special additive to protect seals, Durablend
semi synthetic for cold starting and vehicles under 75,000 miles, Synpower full synthetic for new vehicles "the
ultimate in engine lubrication".

Corroded Battery Cables
Corroded cables and a weak battery cause starting trouble. Have battery and charging system checked if
the engine turns over slowly. Warm weather puts more demand on your vehicles electrical system than cold
weather. It's a good idea to get your battery, alternator, and starter checked before summer vacation travel.

Inspect Belts and Hoses Monthly
Replace worn, glazed or frayed belts. Tighten them when more than ½" of slack can be depressed
between the pulleys. Vehicles with spring loaded belt tensioners require no adjustment. Replace bulging, rotten
or brittle hoses and tighten clamps. If a hose looks bad, or feels too soft or too hard, it should be replaced.
Belts and hoses are one of the main causes of major engine failures due to overheating. Check your belts and hoses
every oil change and replace them at 50,000 to 60,000 miles depending on condition.

Tired Tires
Worn tires are dangerous. Proper inflation, alignment and balance will extend tire life.

Leaking Muffler
Have your car put on a lift occasionally to check the muffler and other parts of the exhaust system.

Old Brake Fluid
Have the brake fluid flushed out and new fluid installed every 24 months or 25,000 miles. Brake fluid gets
moisture contaminated and losses it's ability to seal and lubricate over time. If the fluid in the brake master
cylinder appears dark in color it may be time to replace it.

Windshield Wiper Blades
Don't wait for a rainy day to replace worn blades. Road film, poorly adjusted wiper arms, and rubber deterioration
are the biggest causes for wiper blade failure. Clean your windshield with a good quality glass cleaner and make
sure that the wipers contact the windshield at a 90 degree angle. Test the clearing capabilities of the blade. If
streaking still occurs, replacement of the blade is necessary.

Air Conditioning
Did you know that you burn less gas at highway speeds with your windows up and your air conditioner on than you
do with your windows down and air conditioner off? Government tests prove it. Reduced air drag with closed windows
makes the difference.

Clogged Filters
Scheduled replacement of air, oil gas, fuel, transmission and other filters extend car life and improve
performance. With increased fuel costs, it doesn't take long to more than pay for a new air filter. Think
about this each time you have you vehicle serviced. You will: increase your gas mileage, increase your
horsepower, extend the life of your engine, have easier engine starts, have smoother idles, and provide
smoother acceleration. Protect your engine from abrasive particles, which can cause excessive wear and
premature engine failure. Improve efficiency by providing the proper amount of air required for combustion.

Cooling System
The cooling system in most vehicles should be flushed and new anti-freeze / coolant installed every other year. The
pH conditioner in coolant wears out and the system becomes acidic and contaminated which can cause corrosion of internal
engine parts, radiators, and heater cores.

Alignment
Most vehicles should have their alignment checked every year. The springs and suspension sag from the weight of the
vehicle which changes the alignment angles. This can cause tire wear and handling problems.

Worn Brake Parts
Postponing needed brake service, in addition to being a safety hazard, can escalate the cost of a brake system
overhaul. If your brakes squeak, grind, pulsate, or if the pedal is too low, get them checked right away. Have
your brakes inspected every 10,000 to 15,000 miles for wear. Abnormal wear can be caused by poorly adjusted
rear brakes. Most rear brakes are adjusted when you apply your parking brake regularly on todays vehicles.

Automatic Transmission
Your automatic transmission fluid should be changed every 25,000 miles of normal driving. In most vehicles, transmission
fluid gets contaminated much like your engines, oil and seal additives wear out. Check your vehicles maintenance manual for
specifics on your vehicle.

Engine Cleanliness
One very common sight, during the summer months, is seeing a motorist standing on the side of the road, with the
hood of the car gaping wide open, and billows of steam issuing from the engine cavity. While this could be the
result of a blown radiator, or a worn-out water pump, it has been our experience that it is usually, more commonly, the
result of a ruptured radiator hose, or a broken fan belt.

Fan belts and hoses do wear out with time but far too many of them wear out prematurely because of one thing...oil.
Oil that leaks from the engine, coats the rubber and promotes rapid deterioration. Rubber products, under the hood of
a vehicle, that are exposed to oil and the extreme heat of summer driving may be expected to last only 6 to 8 months
rather than 3 to 5 years.

Not only are the belts and radiator hoses made of rubber but the spark plug wires, vacuum hoses, motor mounts,
electrical connectors, and heater hoses are also made of rubber and rubber products. The oil mixed with dirt
combine to thoroughly coat the entire engine compartment. This, in turn, insulates the engine and can actually
make it run hotter. The main culprit, for oil leaks, is usually the valve cover. In recent years, most auto
makers have not used a gasket but, rather, an RTV silicone which is applied to the valve cover, in place of a
gasket.

The cure for all of this?

Repair the oil leak first.

Valve cover gaskets that work are made to fit these engines.

Then have the engine and engine compartment cleaned.

After that simply use a spray or engine cleaner and rinse 2 to 3 times per year.

It could save you hundreds of dollars and keep you from being that person stalled on the side of the roadway.

Timing Belt Maintenance
In simple terms goes like this. There are basically two types of engines.
One type is known as a non-interference, this means if the timing belt
breaks the engine is able to free wheel without damaging the internal
parts. The other type is known as the interference engine, this means if
the timing belts breaks the piston can make contact with the valves,
resulting in severe damage. Either way, it is important to maintain a good
timing belt. Most cars recommend replacing the belt at every 60,000 or
90,000 miles depending on the vehicle manufacturer.
